The stomach acid makes the stomach a particularly hostile environment for bacteria. It is an too acidic an environment for most microorganisms to survive. In addition there are proteases that will digest most cells.
Quite simply, the bacteria are acid-stable which is to say, they can live just fine in a pH that low (about 2). Bacteria throughout the world have adapted biochemically in order to survive in various extreme environments such as the thermophiles in the springs at Yellowstone National Park.
The stomach contains a highly acidic mixture of enzymes, acids, etc. Specifically, the inside of the stomach is acidic to allow the enzyme pepsin to work at its maximum efficiency. The use of hydrochloric acid (HCl) acidifies to stomach juices to around a pH of 2. This highly acidic environment allows the destruction of bacteria. The acidic nature of the stomach contents can denature bacterial enzymes, DNA, etc. Therefore, I would say that the acidity of the stomach is what helps destroy bacteria, and prevent infections from said bacteria.
By creating a pH which is too low (acidic) for many microorganisms to survive.
may be yes
Yes, the stomach do kill bacteria. But in the presence of Hydrochloric acid (HCl). This acid can be harmful to the human body also if mucous layer lining the internal layer of the stomach and the alimentary canal is destroyed resulting in peptic ulcer.
to kill any bacteria that enters the stomach
Stomach
The answer is Stomach
A large portion of bacteria, though not all, can not survive in a low pH environment such as stomach acid. The bacteria dies from the corresive nature of low a low pH solution.
Yes, hydrochloric acid can kill bacteria. That is one of the roles it plays in the human stomach. However some bacteria, such as E. Coli, can survive a dilute solution of it though.
Stomach acid kills the bacteria
Stomach acid kills bacteria, which is hydrochloric acid.
Antibiotic,antiseptic etc..
certain chemical reactions do kill bacteria for example when bacteria enters the body the stomach contains High concentrations of Hydrochloric acid which destroys the bacteria preventing further damage to the body.
the bacteria is killed by the acid in the stomach.
